If the camera was set to output formats like RGB565 YUYV or SBGGR10,
the resulting image was scrambled due to erroneous interpretations of
horizontal parameter's units.
This patch in fourcc_to_ipu_pix, eliminate also the pixel formats mappings
that, first are not used within mainline code and second, standing at
the datasheets, they will not work properly:
The IPU internal bus support only the following data formatting
(44.1.1.3 Data Flows and Formats):
1 YUV 4:4:4 or RGB-8 bits per color component
2 YUV 4:4:4 or RGB-10 bits per color component
3 Generic data (from sensor to the system memory only)
And format conversions are done:
- from memory: unpacking from other formats to IPU supported ones
- to memory: packing in the inverse order.
So, assigning a packing/unpacking strategy to the IPU for those formats
will produce a packing to memory and not the inverse.
